ohalf of the amount of prescribed medication dosage.
oan amount of air equal to the medication to be withdrawn from the vial should be drawn into the syringe.
onone.

Explanation:

When drawing up medication from a vial into a syringe, drawing an amount of air equal to the medication to be withdrawn helps create a pressure balance in the vial, making it easier to withdraw the correct dose. Twice the amount or half the amount of air would disrupt the pressure balance, and drawing no air might make it difficult to withdraw the medication due to negative pressure in the vial.

Answer:

An amount of air equal to the medication to be withdrawn from the vial should be drawn into the syringe.
